A kind of danger source provided by the invention and environment monitoring warning system, wirelessly remote transmission be monitored
The monitoring data of danger source and its ambient enviroment, and locally carrying out data storage and analysis so that collected danger source
When related data is exceeded, the alert levels residing for comprehensive descision and corresponding alarm response can be made in time, to solve in time
The monitoring, alarming problem of current various danger sources provides powerful.
With reference to shown in Fig. 2, the embodiment of the present invention provides a kind of environmental monitoring alarm method, including：
101st, monitored at least one danger source and its at least one monitoring data of ambient enviroment are obtained.
In this step, for each monitored danger source, a data acquisition unit is set in its vicinity,
The danger source and its at least one monitoring data of ambient enviroment can be acquired.These monitoring data include a variety of different physics
Amount, can reflect danger source and its actual conditions of ambient enviroment comprehensively, so as to determine that alert levels provide reliably to be follow-up
Data source.
102nd, according to monitoring data and its corresponding weight coefficient and upper limit value and lower limiting value, the comprehensive of danger source is determined
Close monitoring data and corresponding comprehensive upper limit value and comprehensive lower limiting value.
In this step, for a variety of monitoring data of each danger source, first determined respectively according to the property of its physical quantity
Then corresponding weight coefficient, upper limit value and lower limiting value further determines that the comprehensive monitoring data and correspondence of danger source
Synthesis upper limit value and comprehensive lower limiting value.
Specifically, the comprehensive monitoring data of danger source and its corresponding comprehensive upper limit value and comprehensive lower limiting value are respectively under
Formula is calculated：
Mx=M1×β1+M2×β2+...+Mn×βn,
MxH=M1H×β1+M2H×β2+...+MnH×βn,
MxL=M1L×β1+M2L×β2+...+MnL×βn,
And MxL ＜ Mxn ＜ MxH；
Wherein, Mx is the comprehensive monitoring data of danger source X, under MxH and MxL are respectively corresponding comprehensive upper limit value and are comprehensive
Limit value；
M1~MnThe respectively n monitoring data of danger source X, β1~βnThe corresponding weight system of respectively n monitoring data
Number, M1H/M1L~MnH/MnL is respectively the corresponding upper limit value of n monitoring data and lower limiting value, and β1+β2+……+βn=1.
It should be noted that those skilled in the art can rule of thumb and big data analysis as a result, and with reference to itself
Actual conditions determine the concrete numerical value of the corresponding weight coefficient of each monitoring data, are not specifically limited herein, the present invention
Embodiment does not limit the concrete numerical value of weight coefficient.
The 103rd, if comprehensive monitoring data are in the range of comprehensive upper limit value and comprehensive lower limiting value restriction, and each monitoring data
When being in the range of the corresponding upper limit value of monitoring data and lower limiting value limit, alarm response is not made；Otherwise, it determines alarm
Rank simultaneously makes corresponding alarm response.
In this step, if the range that the comprehensive monitoring data actually obtained are in comprehensive upper limit value and comprehensive lower limiting value limits
It is interior, and when each monitoring data are in the range of the corresponding upper limit value of monitoring data and lower limiting value limit, illustrate danger source
For each monitoring data in normal range (NR), there is no abnormal conditions, do not need to make alarm response.Otherwise, illustrate danger source
Each monitoring data have the situation not in normal range (NR), i.e., there are abnormal conditions, it is thus necessary to determine that alert levels are simultaneously made corresponding
Alarm response.
Specifically, alert levels are divided into level-one alarm, secondary alarm and three-level in the present embodiment to alarm.
Wherein, if comprehensive monitoring data are not in the range of comprehensive upper limit value and comprehensive lower limiting value restriction or any one
When monitoring data are not in the range of the corresponding upper limit value of monitoring data and lower limiting value limit, if alternatively, | (MxN/Mx (N-
1)) × θ -1 | when≤0.25, determine that alert levels are alarmed for level-one；
If 0.25 ＜ | (MxN/Mx (N-1)) × θ -1 | when≤0.5, it is secondary alarm to determine alert levels；
If | (MxN/Mx (N-1)) × θ -1 | during ＞ 0.5, determine that alert levels are alarmed for three-level；
Wherein, MxN is the comprehensive monitoring data of the danger source X of this acquisition, and Mx (N-1) is the danger source X of last time acquisition
Comprehensive monitoring data, θ is correction factor.
In the present embodiment, the correction factor is obtained according to the history alarm logging of a certain danger source, the history
Alarm logging includes at least history alert levels and corresponding alarm times, for correcting the alarm possibility of danger source appearance.Root
It is learnt according to a large amount of history alert data statistical analysis, most of accident is gradually enlarged from small accident, directly
To developing into major accident.So small accident is accumulated or had larger accident in the past, then weight occurs again
The probability of major break down will increase, it is therefore necessary to be adjusted by correction factor come the alert levels to danger source, make it
More accurate it can objectively reflect that the severity of accident occurs in danger source.
Preferably, when a certain danger source does not have history alarm logging, it is 1 to determine correction factor；When a certain danger source is deposited
In history alarm logging, it is 1.25 to determine correction factor.In this way, when there are during history alarm logging, can will originally belong to
The situation of level-one alarm is promoted to secondary alarm, and the situation for originally belonging to secondary alarm can also be promoted to three-level alarm.
It should be noted that those skilled in the art can rule of thumb and big data analysis as a result, and with reference to itself
Actual conditions determine the concrete numerical value of correction factor, are not specifically limited herein, and the embodiment of the present invention is to the specific of correction factor
Numerical value does not limit.
When a certain danger source is alarmed, and after making corresponding alarm response according to alert levels, the danger is released
The alarm condition in source, but its alert levels and alarm times can be stored as history alarm logging, and alarm is determined for next time
Rank provides auxiliary reference.
A kind of danger source provided by the invention and environmental monitoring alarm method can pass through the correlation of collected danger source
Data, alert levels residing for timely comprehensive descision simultaneously make corresponding alarm response in time, to solve current various danger sources
Monitoring, alarming problem provide powerful.
In the above embodiment of the present invention, all emphasize particularly on different fields to the description of each embodiment, do not have in some embodiment
The part of detailed description may refer to the associated description of other embodiment.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention.
